- relative density
- Density:
- 1.54 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- A gas comparison stereopycnometer was used for the determination of the density and relative density of CMTX 2-carboxymethyloxy-thioxanthone.
The density of the test item at 20ºC was 1.54 g/cm^3 (1540 kg/m^3).
The relative density was 1.54. - Executive summary:
In this guideline (OECD 109) study conducted with GLP certification, the test material (EC 282-803-8) was determined to have a relative density of 1.54.
Reference
The results of the tests on the determination of the density of the test item are given in Table 1.
The individual measurements were obtained with an accuracy of < 0.02 g/cm3. According to the guideline, the density of the test item is given as the mean value.

Density of the Test Item
| Test 1 | Test 2 | Mean | |
| Density [g/cm3] | 1.54 | 1.539 | 1.54 |
Description of key information
Study conducted to recognised testing guidelines with GLP certification.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.54
